Our security details

We know how critical data security is these days. Lead Onion’s platform is hosted by a UK based data-centre. The Lead Onion application is protected by a firewall and data exchanged between yourselves and the application is encrypted in transit. We utilise the services of an independent third-party professional certification company to perform penetration testing, to validate our data security policies and practices. See below for more details.

Does Lead Onion encrypt data in transit?

The connection to this site is encrypted and authenticated using a strong protocol (TLS 1.0, 1.1, 1.2), a strong key exchange (ECDHE_RSA with P-256), a strong cipher (AES_128_GCM) and 2,048-bit keys.

Is Lead Onion protected by a firewall?

Yes. Config Server Firewall (or CSF) is an advanced firewall for Linux distributions and Linux based VPS. In addition to the basic functionality of a firewall – filtering packets – CSF includes other security features, such as login/intrusion/flood detections etc.
